The Connection.ConnectionContext.IPContext.IPNeigbors allows the NSE to specify IPNeighbors associating an IP address to a hardware address that should be configured.

When the Client or NSE are vpp, there needs to be chain elements to set the ip neighbors for that connection (no matter its mechanism).

This is in direct analogy to the already existing connectioncontext/ipcontext/ipaddress.

Helpful notes for implementation:

IPNeighborAddDel can be used to Add/Del IPNeighbors in VPP.
You can retrieve the swIfIndex set by the mechanism chain elements using ifindex.Load. Example of Use.
Use types.ToVPPMacAddress to convert net.HardwareAddr to the govpp ethernet_types.MacAddress
Once implemented, please add to the connectioncontext/client.go and connectioncontext/server.go.

Running end to end can be done using cmd-forwarder-vpp.
